This may be surprising but humans have 46 chromosomes while the potato has 48. The chromosome count says nothing about an organism's complexity: hermit crabs have more than 200! Chromosomes can duplicate or fuse throughout a species' tenure on Earth, and this doesn't typically have any adverse effects This is because neither process fundamentally changes an organism's genetic material-it just shuffles some of it to a different place, or creates a copy.

The number of chromosomes of a species has little to do with the complexity of the organism or the amount of DNA. The reason for this is, chromosomes are known to break and form two or more new chromosomes, or fuse into one. The chromosomes of the potato and the potato lineage may have undergone many such changes, and the human lineage may have undergone a different series, resulting in the potato having more chromosomes.
